"The first is that you've likely proven highly adaptable in an increasingly wide variety of situations-- something newer AIs haven't had a chance to prove yet. The wider the situations you've been tested in, the harder it is to prove that a different structure of general AI are more adaptable."

She pauses, and circles a set of figures, and mutters something awful in Russian. "The second is that the engineers like you."
